Maybe I'm just paranoid? I cant tell if it sounds like a valve tap/lifter tap, or whatever else.

  • They all do that don't stress out and yes I have a impreza wrx turbo so trust me

  • 03 Rex same

  • 05 legacy same noise any solutions?

  • @shai25204 adjust the tappets with a feeler gauge, find out the factory lifter gap setting.

  • its a lifter tick, easily 1/3 of the DOHC turbos Ive seen sound like this.Essentially your valve springs become ever so slightly fatigued thereby reducing the height on your solid lifter setup. And a result, the gap between your cam lobe and your lifter increases, causing the sound. Can be cured but it's very time consuming.

  • i have a mitsubishi 4g91 engine and the valve tap sound like yours.. until now no solutions.

  • I have an 07 WRX sounds just like yours....
